PetSafe ScoopFree Clumping Self-Cleaning Litter Box (ZAL00-17761)

Cat owners who want to keep using their own clumping litter

This ScoopFree rakes your own clumping litter into a covered waste bin ten minutes after your cat leaves, with no disposable trays to buy. The litter tray, waste bin and bin cover are dishwasher safe and the rake lifts out on two thumbscrews for hand washing. PetSafe's guide says to leave it unplugged and scoop by hand until a kitten is at least six months old.

The ScoopFree that does not need PetSafe's trays

Amazon lists this as the PetSafe ScoopFree Clumping Self-Cleaning Litter Box in grey, model number and manufacturer part number ZAL00-17761, UPC 729849177628. The quick start guide supplied with the listing names two models on its back page, PAL00-17762 and ZAL00-17761, and carries the copyright of Radio Systems Corporation, 2023. PetSafe's own product page uses the same item model number. Amazon's details field lists the manufacturer as "Waste Management" while PetSafe's guide credits Radio Systems Corporation; we report both and do not try to explain the difference.

The important distinction from PetSafe's older ScoopFree boxes is the consumable. This one has a washable litter tray and a washable waste bin instead of a sealed disposable tray. The guide says it is designed to work with most litter types and that PetSafe recommends clumping clay litter or its own ScoopFree Premium Crystal Litter. The listing puts it more simply: no trays needed.

What arrives, per PetSafe's page, is the litter box system, a power adaptor, a quick start guide and a one-year warranty. The guide's parts diagram names the power adaptor, litter tray, waste bin cover, waste bin and rake. A hood is not included: PetSafe sells a separate ScoopFree Clumping Litter Box Hood and Accessory Bundle.

The kitten rule is the one hard restriction in the guide

PetSafe prints it twice in the first four pages. The introduction says: "Important: If you have a kitten, leave the litter box unplugged and scoop waste manually until she is a least 6 months old." The setup step repeats it: "Important: If you have a kitten, leave the litter box unplugged until she is at least 6 months old." So with a kitten in the house this is a manual litter box for months, not an automatic one.

The same page adds a suggestion for young or small cats: put a box or step next to the litter box to make getting in and out easier. And for nervous cats generally, the guide says that while the box is quiet when running and only runs after use, it may be worth leaving it unplugged until a skittish cat is used to it, and to place the new box beside the old one and let the old one get dirty.

We could not find a cat weight limit in the quick start guide, and the guide points to a separate PetSafe customer care guide for the full safety instructions, which we did not read. Amazon's details field lists a "Weight Capacity Maximum 20.2 pounds" with no matching maker figure we could check. If your cat is large or very small, read PetSafe's customer care guide for this model before buying rather than relying on either of those numbers.

Litter choice, fill lines and whether to use a bag

The fill instruction is short but has a detail people skip: the manual asks you to keep the litter level between the min and max fill lines shown inside the litter tray. Both lines are moulded into the tray. Too little or too much changes how the rake works, so check them rather than eyeballing the depth.

The waste bin can be run two ways. The guide says it is easy to clean and can be used unlined to reduce plastic waste, or lined with an 8-to-10-gallon trash bag if you prefer. If you line it, the guide asks you to make sure the bag does not interfere with the movement of the waste bin cover or the rake, and to push the bin all the way back in. That is a common cause of a box that stops raking, so it is worth getting right the first time.

PetSafe's page says the design gives "3x better odor control by trapping waste and unpleasant smells in its covered bin", and that high walls reduce litter tracking. Those are the maker's claims, published without test conditions in what we read, and we do not repeat them as measured facts.

A ten-minute delay, one button and five light codes

Sensors inside the box detect when your cat is present. When the cat leaves, the rake button blinks blue and a ten-minute countdown starts, which PetSafe says is designed to give the litter time to clump or absorb waste before the rake moves. When the countdown finishes the rake pushes solid or clumped waste into the waste bin. If the cat comes back during the countdown the timer stops and resets when the cat leaves again. That ten-minute delay is half the twenty minutes used on PetSafe's crystal-tray ScoopFree models, which is worth knowing if you are comparing the two.

There is one button and it does two jobs: press it to run a rake cycle at any time, and press it again while the rake is moving to pause it. The light codes are published in the guide. Solid blue means powered, normal and rake at home. Blinking blue means the timer is counting down or the rake is moving. Fast blinking blue means the rake is paused because you pressed the button mid-cycle. Blue and red blinking means a mechanical error during the cycle: clear obstructions near the rake and press the button so it finishes and returns home. Solid red means clear obstructions and clean the sensors, and contact PetSafe customer care if it persists.

There is no app, no Wi-Fi and no account here, and nothing in the guide describes a weight scale or usage tracking. Power is a plug-in adaptor into a socket on the back of the box, with clips on either side to secure the cable.

Emptying weekly, and the every-few-weeks strip-down

Routine upkeep is two things. The guide says to empty the waste bin when it starts getting full and add more litter when needed, staying within the fill lines. Both the listing and PetSafe's page describe that as a weekly waste bin empty; the guide itself does not attach a number of days to it, so treat weekly as PetSafe's marketing guidance and the "when it starts getting full" line as the actual instruction.

The deeper clean is described as every few weeks. Unplug the box, slide the waste bin out and dispose of the waste, lift the waste bin cover and slide it forward out of the frame, open the rake covers, release the rake by turning the left and right thumbscrews a quarter turn, lift the rake straight up and out, then lift the front of the frame, remove the litter tray, set the frame back down and tip the used litter out of the tray using its front and back handles.

Washing is where this model earns its keep. The guide says the litter tray, waste bin and waste bin cover can be washed by hand or in your dishwasher, and that the rake is not dishwasher safe and should be hand-washed. The frame is wiped with a cloth or sponge, mild soap and water, and you are told to make sure the sensors inside the frame are clean and unobstructed. The guide's warning is the same one PetSafe prints on its other boxes: "Do not use bleach or chemicals to clean; the odor may repel your cat." Everything has to dry thoroughly before reassembly.

Size, warranty and what you still need to read

Published dimensions differ between the two sources. PetSafe's specification block gives 21.1 x 10.7 x 29.0 inches; Amazon's table gives 20.6"L x 10"W x 28.4"H and an item weight of 6.6 pounds. Both describe a tall, narrow box rather than a wide one, so the constraint in most homes will be height and the room you need above it to lift the frame and pull the rake out. PetSafe does not publish a weight figure we could compare with Amazon's 6.6 pounds.

The warranty line on the back of the quick start guide is a plain "1-Year Limited Warranty", and PetSafe's page lists a one-year warranty among what is included plus a 45-day return window on direct purchases. Amazon's details field also says 1 Year Limited Warranty. As always, the seller and condition on the offer you select determine what you can actually claim, so check those before you buy.

One thing to do before first use: the quick start guide is a setup card, not the full manual. It says twice to see the customer care guide for the important safety instructions, including those relating to cat litter waste and toxoplasmosis. PetSafe links the product manual from the support section of the product page. Read that document rather than relying on the card that comes in the box, and rather than on this page.
